Pot-limit 5 card Draw. Lots of donkeyz calling with shorts, drawing to straights and baby flushes (and still scared of boats when they hit), basically: suckers for a big raises (like in Holdem

). Unfortunately, fishes go bust very fast, almost everybody thinks that draw poker has more randomness than holdem but in fact this game is more stable, less variance and less bad beats (but if bad beat comes, it's often spectacular and it's easy to go on tilt when your pat A flush gets busted by miracle 3 card draw that filled up, cracking AA with QJ in holdem is NOTHING compared to draw poker bad beats).
